Simrad AP50 Autopilot

External Alarm (Wheelmark System)

Note ! Wheelmark installation requires separate monitoring of power

failure.

Note that Simrad does not supply an external alarm unit,

required for a Wheelmark system. The diagram below shows

how an arrangement can be made. The buzzer shall provide

between 75 and 85 dB of power.

The relay voltages are determined by the autopilot Mains supply

and the alarm voltage supply.

2.10 Drive Unit Installation

The relation between drive units, drive unit voltage, input

voltage, drive output, and interfacing to steering gear are shown

in Table 2-2 and Table 2-3. The AP50 system detects whether a

reversible motor or a solenoid is connected and outputs the

correct drive signal automatically.

Refer to the connecting diagrams for the different drive units on

pages 22 through 24.

Installation instructions for the drive units are found in the

manuals for the individual units.

The maximum drive current capabilities of the J50 and J50-40

Junction Units are different. Use the table below as a reference

and observe the notes.
